The Connection Between Common Viruses and Voice Loss

Laryngitis, an inflammation of the voice box (larynx), often results in voice loss or hoarseness. If you're wondering what virus causes you to lose your voice, the most common culprits are those responsible for upper respiratory infections, such as the common cold and influenza. These viruses lead to swelling of the vocal cords, impairing their normal function and causing voice changes. Typically, this condition resolves on its own within a week, but resting your voice and staying hydrated can aid recovery.
